Standard changes are pre-authorized, low-risk, and well-understood changes that are implemented without needing additional authorization for each occurrence. The 'service request management' practice is designed to handle pre-defined, user-initiated requests. Because standard changes follow an established and pre-approved procedure, they are often initiated through a service request. This allows them to be fulfilled efficiently, often by the service desk, aligning perfectly with the purpose of service request management. For example, a request to install a pre-approved software application on a user's laptop is a standard change fulfilled via a service request.

A. An emergency change is implemented to resolve an incident or security issue and requires an expedited, urgent authorization process, not a routine service request.

B. A normal change requires scheduling, assessment, and authorization through the formal change enablement process and is not managed as a simple service request.

C. 'Application change' describes the object of the change, not the process type. An application change could be standard, normal, or emergency, making this option too general.

Section 5.2.4

Change enablement: "Standard changes are pre-authorized changes that are low risk

relatively common and follow a procedure or work instruction... When the procedure for a standard change is created or modified

there should be a full risk assessment and authorization as for any other change. This authorization is only needed once

and not for each occurrence of the standard change. Standard changes are often initiated as service requests..."

Section 5.2.15

Service request management: "The purpose of the service request management practice is to support the agreed quality of a service by handling all pre-defined

user-initiated service requests in an effective and user-friendly manner... Some service requests are in effect pre-authorized changes (for example

a request to install a standard application)."
